Perfect for creating a side navigation that automatically updates the active/inactive states depending on the scroll position. Supports both horizontal and vertical page scrolling.
How to use it:
To get started, just include the anchor-trigger.js at the bottom of the webpage and we’re ready to go.
- listOfAnchorNames: array containing the names of anchors to watch
- callback: function to callback when within a certain anchor
var obj = AnchorTriggre( listOfAnchorNames, callback, [options] )
// tags to query as anchors. query: 'a', // Only call callback when anchor has changed. onlyOnChange: true / // fraction of page (top to bottom or left to right) to trigger new area. fraction: .5, // Delay to throttle calls during scroll delay: 50, // The element we are watching for scroll. bind: window, // Direction of scroll // 'top' or 'left' flow: 'top', // called even when trigger remains the same. alwaysCallback: undefined
